Find the measure of the arc. MFD=
Answer:
124
Step-by-step explanation:
The measure of arc mFD in the above figure is 130°.
The arc of a circle is a portion of the circumference of that circle. It's outlined as a continuous curve that connects two points on the circle. The two endpoints of the arc are known as the arc's endpoints, while the center of the circle is appertained to as the arc's center.
The extent of an arc is directly proportional to the size of the angle it subtends at the center of the circle. However, the arc will be longer, and if the angle is inferior, If the angle subtended is substantial.
From the figure, it is evident that ∠AOC = 90° and ∠AOB = 140°.
As it is known that the whole angle is 360°.
So,
∠AOB + ∠AOC + ∠BOC = 360°
140° + 90° + ∠BOC = 360°
∠BOC = 360° - 140° - 90°
∠BOC = 360° - 230°
∠BOC = 130°
So,
mBC = 130°
Also, as evident from the figure,
mFD = mBC
So,
mFD = 130°.
Therefore, the measure of arc mFD is 130°.

What is the area, in square meters, of the shaded region in the diagram?
Answer:
Notice that the side length of the square is 38 m.
area of square = (side length)2 = (38 m)2 = 1444 m2
Notice that the diameter of the circle is 38 m .
And its radius = diameter / 2 = 38m / 2 = 19 m
area of circle = pi * radius2 = pi * (19m)2 = pi * 361 m2 ≈ 1133.54 m2
So......
area of shaded region = area of square - area of circle
area of shaded region ≈ 1444 m2 - 1133.54 m2
area of shaded region ≈ 310.46 m2
Step-by-step explanation:
Notice that the side length of the square is 38 m.
area of square = (side length)2 = (38 m)2 = 1444 m2
Notice that the diameter of the circle is 38 m .
And its radius = diameter / 2 = 38m / 2 = 19 m
area of circle = pi * radius2 = pi * (19m)2 = pi * 361 m2 ≈ 1133.54 m2

is bolted to the ground 48 m from the base of
the tower. If the wire makes an angle of 14°
with the ground. What is the length of the
guy wire? Round your answer to the nearest
hundredth of a meter.
Answer:
49.47 m
Step-by-step explanation:
You will need to use the cosine function
which is the ratio adjacent side/hypotenuse
So, let x = length of guy wire
then cos 14 = 48/x
x cos 14 = 48
x = 48/cos 14
= 49.47 m

covert this repeating decimal into a fraction
Answer: 4311/9900 or 479/1100
Step-by-step explanation:
Okie so in order to do this, we need to get rid of the repeating part of the decimal
==============================================================
Right now we have x = 0.435454545454...
If we multiply this by 100, we get
100x = 43.545454545454
And if we multiply by 10000 we get
10000x = 4354.5454545454
==============================================================
Subtract the two equations
10000x = 4354.5454545454
100x = 43.545454545454
------------------------------------------------- (notice: the repeating part will cancel out)
9900x = 4311
x = 4311/9900
If you simplify the fraction you get: 479/1100
The fraction that represents the repeating decimal is
[tex]\frac{479}{1100}[/tex]
Given :
A repeating decimal [tex]0.4354545454...............[/tex]
there is bar at 54 , so 54 is repeating
We need to convert this decimal into fraction
54 is repeating so we multiply by 100
Let x= [tex]0.4354545454...............\\[/tex]
[tex]100x=43.54545454...............[/tex]
Now we subtract x from 100x
[tex]100x=43.54545454...............\\ x= 0.4354545454...............\\-----------------------------------------\\ 99x=43.11[/tex]
Now divide both side by 99
[tex]x=\frac{43.11}{99} \\[/tex]
multiply top and bottom by 100 to remove the decimal
[tex]x=\frac{4311}{9900} \\Divide \; top \; and \; bottom \; by 9\\x=\frac{479}{1100}[/tex]

The stock market in 2008 has gone through drastic changes. On December 3rd, 2008 the Dow Jones Industrial Average (DJIA) closed the day at 8,591.69 points. On December 4th of the same year, the DJIA decreased by 2.51% of its December 3rd closing. On December 5th of the same year, the DJIA increased by 3.09% of its December 4th closing. Determine what the DJIA closed at on December 5th. Round your answer to the nearest point.
a.
8,631.78 points
c.
8,634.86 points
b.
8,750.35 points
d.
9,079.49 points
Answer:
C, 8,634.86
Step-by-step explanation:
Starting with 8,591.69
2.51% of 8,591.69 is 215.651419
subtract that from 8,591.69 and you get 8376.038581
3.09% of 8376.038581 is 258.819592153
258.819592153+8376.038581=8634.85817315
8,634.86 is your final answer

A= 7x + 24°
B = 3x + 92
A=
Answer:
X= 6.4 ∠A=68.8
Step-by-step explanation:
We know that these 2 angle must equal 180 so we use the equation:
180=7x+24+3x+92
OR
180=7x+3x+24+92
Then, we add like terms (both variable and numbers)
180=10x+116
After that, we solve
180=10x+116
-116 -116
__________
64=10x
________
64/10 = x
________
6.4=x
Now that we have found x, we can plug in x to figure out the new equation to find the angle of A (or B).
∠A= 7(6.4)+24
If we solve that, it would be:
∠A=44.8+24
___________
∠A=68.8

A ball is thrown into the air with an initial upward velocity of 48 ft/s. It height h in feet after t seconds is given by the function h (t)=-16t^2+48t+4.
What is the ball's maximum height?
Answer:
40 feet (after 1.5 seconds).
Step-by-step explanation:
The height h of the ball after t seconds is modeled by the function:
[tex]h(t)=-16t^2+48t+4[/tex]
And we want to determine the ball's maximum height.
Since the given function is a quadratic, the maximum height occurs at the vertex point.
For quadratics, the vertex point is given by the formulas:
[tex]\displaystyle \Big(-\frac{b}{2a},f\Big(-\frac{b}{2a}\Big)\Big)[/tex]
In this case, a = -16, b = 48, and c = 4.
Therefore, the t-coordinate at which the vertex occurs is:
[tex]\displaystyle t=-\frac{48}{2(-16)}=\frac{48}{32}=\frac{3}{2}[/tex]
So, the maximum height occurs after 1.5 seconds.
Then the maximum height will be:
[tex]\begin{aligned}\displaystyle h\Big(\frac{3}{2}\Big)&=-16\Big(\frac{3}{2}\Big)^2+48\Big(\frac{3}{2}\Big)+4\\\\ &=-16\Big(\frac{9}{4}\Big)+24(3)+4\\\\&=-4(9)+72+4\\\\&=40\text{ feet}\end{aligned}[/tex]
So, the maximum of the ball is 40 feet (after 1.5 seconds).
